I've begun documenting this project to provide everyone with an easy entry point:

Behold, a groundbreaking innovation: an over-engineered #ESP32 module to control your #Daikin aircon! Because, clearly, toggling the switch manually was way too mainstream.
Let's all applaud this feat of #technology, which ensures you'll never have to rise from your throne of #laziness again.

Someone asked how play multiple simultaneous CD-quality WAVs from an SD card to I2S DAC on ESP32 in CircuitPython. Turns out: possible! Can get a bit glitchy if doing USB stuff tho https://www.youtube.com/watch?v=97OA6L9PLCg

Zephyr provides k_thread_stack_space_get() and sys_heap_runtime_stats_get() for real-time memory monitoring, which can help you detect memory leaks.
See my tutorial to see how to use them: https://shawnhymel.com/2830/monitoring-stack-and-heap-usage-in-zephyr-how-to-detect-memory-leaks/

Mein neues Lieblingsthema #meshtastic
Was ich mich frage:
Die Nodes laufen ja alle auf bekannten Mikrocontrollern, z. B. dem #esp32 und wir können sie programmieren, z. B. über die #arduino IDE oder #platformio
Können wir dann auch eigene Programme schreiben, die auf die Meshtastic-Funktionen (senden, empfangen usw.) zugreifen?
Gibt es dafür #libraries ?
Würde da gerne etwas im Zusammenhang mit #geocaching programmieren.
Weiß jemand was? Habe bisher im Internet nichts zu dem Thema finden können, außer der Library „Meshtastic-arduino“
https://github.com/meshtastic/Meshtastic-arduino
Die dient aber nur dazu, Meshtastic-Nodes über #serial oder #bluetooth zu steuern, also nicht direkt das, was ich suche.
I have half a dozen new #ESP32 devices lying around, and I'm not sure what to do with most of them
I wanna try and use one to make my air filter smart, and maybe turn two or three into #EspHome Bluetooth Proxies to use them for indoor location tracking through Bermuda
That leaves me with still a few spares, any ideas for cool projects I could use them for?
Two Birkenhackers successfully made a 32x32 LED panel work with #wled on a #esp32 on Tinker Night last Wednesday. Hopefully we can increase the size of the array on the next Tinker Night!
We even used our Macintosh LCIII connected to the internet, to search how to wire it up. Since this machine is not powerful enough to display ads, we were able to work without distraction.
Questions, 4 of 3 (Told ya!)
I want to use a piezo knock sensor so I can tap on the glass and turn the lights on without breaking the door seal. Can I mount the piezo anywhere in the cabinet, or does it need to be on the door.
There are 14 millions piezo sensor tutorials on the web, but every one of them starts with "What's an Arduino?" and and ends with the piezo plugged into a breadboard. Nobody explains the mechanical considerations.

Questions, 3 of 3 (for now).
I want to drive an LCD panel (not pictured). The one I bought uses SPI. If I want to run animations, it needs ~40 MHz. Is it possible to run SPI at that speed through a one meter wire, or should I put another MCU on the back of the display and run USB to it?
I'm leaning toward another MCU.
Thanks.

Questions, 2 of 3.
What's the best way to attach a wire to a LED strip? When I just solder them on, they eventually break off. Could I make a small PCB and bond the strip to that? Should I print some kind of clamp/strain relief thing to hold the wire end in place? If I do the PCB, I'll throw some capacitance on.
I have about 2 cm between the end of the strip and the end of the channel.
Thanks.
